Distal Tibia Allograft Augmentation for Glenoid Deficiency

Treatment of shoulder instability due to glenoid bone loss can be challenging. Common reconstructive techniques include the Latarjet procedure (coracoid transfer) or glenoid augmentation using autograft iliac crest. Dr. Matthew Provencher has described an alternative that uses fresh distal tibia allograft (DTA).¹ The lateral portion of the distal tibia is a great match to the patient’s glenoid because it has similar curvature, dense bone, and cartilage.

The Distal Tibia Allograft Workstation is used along with the instrumentation and cannulated screws from the Arthrex Glenoid Bone Loss Set. It allows the surgeon to use trials to determine the desired size and shape of the bone block and then provides a set of simple cutting guides to precisely machine the DTA to match the trial.
